The presented article presented data confirming the antioxidant properties of ferulic acid, which is associated with inhibition of the intensity of lipid peroxidation in the body of day-old turkeys, expressed in a decrease in the concentration of its cytotoxic products formed at different stages of the peroxide cascade: isolated double bonds (IDB) by 1,2 times, diene conjugates (DC) 1,6 times (p<0,001,.1,1), triene conjugates (TC) and oxodienic conjugates (ODC) 1,4 times, Schiff bases (SB) 12,02 times compared to the control. This helped to optimize the central metabolic processes, in particular carbohydrate metabolism. The paper analyzes these changes, presents and explains their relationship with the increase in quantitative and qualitative indicators of young turkeys at the early stages of ontogenesis. Thus, the superiority of the experimental group over the control of hatching turkey poults was 0,01% (p<6,66), the hatchability of eggs was 8,23% with a tendency to an increase in live weight of individuals of day-old age by 0,5%, the score according to the «Pasgar» scales and «Optistart» by 0,05 (p<1,0) and 0,001 points (p<XNUMX), respectively.
